Electric generating plants transport large amounts of hot
water through metal pipes, and oxygen dissolved in the water can
cause a major corrosion problem. Hydrazine (N2H4) added to the
water prevents this problem by reacting with the oxygen:
N2H4(aq) + O2(g) ⟶ N2(g) + 2H2O(l)
About 4×107 kg of hydrazine is produced every year by reacting
ammonia with sodium hypochlorite in the Raschig process:
2NH3(aq) + NaOCl(aq) ⟶ N2H4(aq) + NaCl(aq) + H2O(l)
ΔHrxn ° = −151 kJ
(a) If ΔH°f of NaOCl(aq) = −346 kJ/mol, find ΔHf° of N2H4(aq).
(b) What is the heat released when aqueous N2H4 is added to
5.00×103L of water that is 2.50×10−4 M O2?
